You have received a letter from your English-speaking friend Mark, who writes:​

We are doing a report in my science class about air pollution. I wanted to ask you a few things about it. What causes of air pollution do you have in your country? Does it affect people's health, and if so, how? What's the best way to fight air pollution?​

Write her a letter and answer her 3 questions. Write 100–120 words. Remember the rules of letter writing.​
